Enhancement of the pulsed terahertz radiation generated from a lens-coupled InAs thin film excited by a femtosecond laser is reported. A Si hemispherical lens was used as a lens coupler and attached to the substrate-side of a 520-nm-thick InAs film, grown on a Si substrate. An enhancement factor of...
